positive traction ?
« on: February 8, 2005, 09:09:35 AM »
I have a 86 dodge d 150 2wd that I've owned for 12 years . I have installed 3/4 ton springs on it so it could handle more weight and 32" mud tires.
 My neighbor has extra positive traction rear end he says will fit it. The numbers on it are  3723599A   10325
what ever that means.

My question is... if I install this rear end , what kind of top end speed will I have ?
I still have to drive on freeways sometime and still want 70-75 mph.

you really need the gear ratio of it.. most of the time there is a tag saying the ratio on one of the rear cover bolts.

If the gear ratios are the same then nothing would change as far as top speed. Like taz man said check the gear ration. It should have a tag on it if not then pull the cover and see what is stamped on the ring gear.

Since the axle is out of a vehicle, just pop the diff cover off and count the # of teeth on the pinion and ring gear.  Divide the # of ring teeth by the # of pinion teeth for your gear ratio.
